Answer:

Ok, so we have a square with sides of 14 inches. :)

The diagonal splits the square into two by the corners, so it forms two right triangles!

We can use the Pythagorean theorem on the right triangle to get:

14^2 + 14^2 = x^2

BTW, x is the length of the diagonal :)

So, 196 + 196 = x^2 = 392

Sooo, x is just the square root of 392 :)

\sqrt{392}\\ = 19.7989898732, which rounds to 20

Felicia is buying a Crockpot that retails for $125. She has a coupon for $40 off of any item over $100. Calculate her percent sa
Juliette [100K]

Answer:

32%

Step-by-step explanation:

Given

Cost of Crockpot = $125

Coupon = $40

Coupon applies on items greater than $100

Required

Percent saved if coupon is applied.

If she applies coupon on the Crockpot, then she'll be saving $40.

Percent Savings = Amount Saved / Total Amount

Percent Savings = $40/$125

Percent Savings = 0.32

Convert to Percentage

Percent Savings = 0.32 * 100%

Percent Savings = 32%.

Hence, she'd save 32% if she applies the coupon of $40 on the Crockpot

A Square was altered so that one side is increased by 9 inches in the other side is decreased by 2 inches.The area of the result
LekaFEV [45]

Let s represent the length of any one side of the original square.  The longer side of the resulting rectangle is s + 9 and the shorter side s - 2.

The area of this rectangle is (s+9)(s-2) = 60 in^2.

This is a quadratic equation and can be solved using various methods.  Let's rewrite this equation in standard form:  s^2 + 7s - 18 = 60, or:

s^2 + 7s - 78 = 0.  This factors as follows:  (s+13)(s-6)=0, so that s = -13 and s= 6.  Discard s = -13, since the side length cannot be negative.  Then s = 6, and the area of the original square was 36 in^2.

Write an expression to represent the sum of three consecutive even numbers. Let C represent the first number in the series
Anna [14]
Let, the first number = C
second number will be = C + 2   ['cause next will be odd so we can't include that]
Third number = C + 4

Now, their sum would be:
C + C+2 + C+4 = 3C + 6

In short, Your Answer would be 3C + 6

Hope this helps!
